Dnepr (rocket)
The Dnepr rocket (russian: Днепр, translit=Dnepr; uk, Дніпро, translit=Dnipró) was a space launch vehicle named after the Dnieper River. It was a converted ICBM used for launching artificial satellites into orbit, operated by launch service provider ISC Kosmotras. The first launch, on April 21, 1999, successfully placed UoSAT-12, a 350 kg demonstration mini-satellite, into a 650 km circular Low Earth orbit. History The Dnepr was based on the R-36 (missile), R-36MUTTH Intercontinental ballistic missile (ICBM)called the ''SS-18 Satan'' by NATOdesigned in the 1970s by the Yuzhnoe Design Bureau in Dnepropetrovsk, Ukrainian SSR. The Dnepr control system was developed and produced by the Khartron, JSC "Khartron", Kharkiv. The Dnepr was a multistage rocket, three-stage rocket using storable hypergolic liquid propellants. The launch vehicles used for satellite launches have been withdrawn from ballistic missile service with the Russian Strategic Rocket Forces a ...

Dombarovsky (air Base)
Dombarovsky (also given as Dombarovskiy and Tagilom) is a military airbase northwest of the village of Dombarovsky, near Yasny in Russia's Orenburg Oblast. Operated by the Soviet Air Forces and later by the Russian Air Force, it hosted fighter interceptor squadrons and hosts an ICBM base (which has been adapted for commercial satellite launches) with a supporting helicopter base. The site is divided into three sites: * The former main runway and dispersals: * The current ICBM base: * The current ICBM support helicopter base: home to the 84th Independent Helicopter Squadron of the 13th Red Banner Rocket Division Interceptor base The facility featured three revetment compounds. The 412th Fighter Aviation Regiment (412 IAP) flew from the base with Sukhoi Su-9 (Fishpot) aircraft in the early 1970s. The regiment replaced it in 1978 with the Mikoyan-Gurevich MiG-23M (Flogger-B). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2014 In Spaceflight
In 2014, the maiden flight of the Angara A5, Antares 120 and Antares 130 took place. A total of 92 orbital launches were attempted in 2014, of which 88 were successful, two were partially successful and two were failures. The year also saw seven EVAs by ISS astronauts. The majority of the year's orbital launches were conducted by Russia, the United States and China, with 34, 23 and 16 launches respectively. Overview An Ariane 5 ES launched the ''Georges Lemaître'' Automated Transfer Vehicle, the last one of the series, which also marked 60 successfully completed Ariane 5 launches in a row. On 22 August 2014, Arianespace launched the first two Full Operational Capability Galileo satellites for the European satellite navigation system. A number of significant events in planetary exploration occurred in 2014, including the entry of the Rosetta spacecraft into orbit around the comet 67P/Churyumov–Gerasimenko in August 2014 and the deployment of the Philae lander to its su ...

Geocentric Orbit
A geocentric orbit or Earth orbit involves any object orbiting Earth, such as the Moon or artificial satellites. In 1997, NASA estimated there were approximately 2,465 artificial satellite payloads orbiting Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center. More than 16,291 objects previously launched have undergone orbital decay and entered Earth's atmosphere. A spacecraft enters orbit when its centripetal acceleration due to gravity is less than or equal to the centrifugal acceleration due to the horizontal component of its velocity. For a low Earth orbit, this velocity is about ; by contrast, the fastest crewed airplane speed ever achieved (excluding speeds achieved by deorbiting spacecraft) was in 1967 by the North American X-15. The energy required to reach Earth orbital velocity at an altitude of is about 36 MJ/kg, which is six times the energy needed merely to climb to the corresponding altitude.

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called Transponder (satellite communications), transponders. Many satellites use a Satellite bus, standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming Satellite constellation, constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio Broadcast relay station, relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Observation Satellites Of Russia
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft Launched By Dnepr Rockets
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
